Replacing repeated captures

Question

This is sort of a follow-up to Python regex - Replace single quotes and brackets thread.

The task:

Sample input strings:

RSQ(nam         


        

Answer 1

You can indeed use the regex module and repeated captures. The main interest is that you can check the structure of the matched string:

import regex

regO = regex.compile(r'''
    \w+ \( (?: name\['([^']*)'] (?: ,[ ] | (?=\)) ) )* \)
    ''', regex.VERBOSE);

regO.sub(lambda m: 'XYZ(' + (', '.join(m.captures(1))) + ')', s)

(Note that you can replace "name" by \w+ or anything you want without problems.)
